Constant data: G (gravitational constant) = 6.67 * 10 ^ -11 m3 / (kg * s2); by condition M (mass of the Sun) = 2 * 10 ^ 27 t = 2 * 10 ^ 30 kg; R (average radius of the Sun) = 7 * 10 ^ 8 m.
Free fall acceleration at a height close to the Sun’s surface is calculated by the formula: g = G * M / R2.
Let’s perform the calculation: g = 6.67 * 10 ^ -11 * 2 * 10 ^ 30 / (7 * 10 ^ 8) ^ 2 = 272.2 m / s2.
Answer: Acceleration of free fall on the Sun is 272.2 m / s2 (2.72 * 10 ^ 2 m / s2).
